You enquired about support for an architecture within Plan 9 on a Plan 9 list so the context was clear and I reply with the relevant architecture string to help you locate it, but get a little lecture about Arm's naming scheme (come to think of it, what are Thumb-1 and Thumb-2 called?). Next time, I'll insist on the 27B/6.

From https://developer.arm.com/documentation/den0024/a/Introduction?lang=en

"AArch64 is the name used to describe the 64-bit execution state
of the ARMv8 architecture. AArch32 describes the 32-bit execution
state of the ARMv8 architecture, which is almost identical to ARMv7.
GNU and Linux documentation (except for Redhat and Fedora distributions)
sometimes refers to AArch64 as ARM64."

I would agree that you could use the therm ARM64 as a synonym of
Aarch64, but giving me just that response... It isn't even funny.
